The armed individual who opened fire at Trump's dinner with journalists, Cole Allen, is suspected of sending a threatening letter to family members 10 minutes before acting. According to sources cited by US media, in this document he described himself as the "Friendly Federal Killer" and expressed his intention to attack officials of the Trump administration.

In the message, Allen mentioned "administration officials" as targets, listing them by priority. A US official said the document was sent about 10 minutes before the shooting.

"The first thing I noticed entering the hotel was a sense of arrogance. I walked in with several weapons on me, and no one suspected anything," he had written.

He also used harsh language and severe accusations against the president, while claiming his actions had ideological and political motives. In the document, Allen also mentioned the method of using weapons, claiming he aimed to minimize casualties, although he acknowledged being willing to cause greater damage to achieve his objectives.

"Turning the next page is when you yourself are oppressed. I am not the person raped in a detention camp. I am not the fisherman executed without trial. I am not a schoolchild blown up, or a hungry child. Turning the next page when 'someone else' is oppressed is not Christian behavior; it is complicity in the oppressor's crimes," he wrote in the letter.

He referred several times to his Christian faith, justifying the action as a response to perceived injustices. He also mentioned political issues, including immigration policies and anti-drug trafficking operations. According to authorities, the document was handed over to the police by a relative of his.

Meanwhile, Acting Attorney General Todd Blanche stated that investigators believe Allen had traveled by train from Los Angeles to Washington, via Chicago, possibly to avoid stricter air travel checks. / Top Channel
